On The Piste!!

Good Question!!
We ski every year and have seen a couple of areas.
La Tania - Foot of 3 valleys ski area 1300m Ski in & Out elec and service point I am going there this Jan with a mate to check out the aire as a location for the 2007 season if you go to
www.latania.co.uk there is a link to pictures and on one of the maps you can see a reference to the camping car area. Left of main cable car fron village. Will let you know.
Les Gets - Easily linked into Morzine avoriaz and Portes Du Soleil. We were there in the summer of 2004 for the Mountain biking world cup spectating i must add, though we did take our bikes and loved the VVT (MTB) routes. There seemed to be a big car park at the lower end of the village which was populated with M/H this I was assured by the locals was the norm and in the winter it only gets bigger. I couldn't see any elec or a service point but I am sure there was one.
La Plagne - Plange Soleil area. When we skiied there two years age there was a big area below one of the lifts in this area, we were mere tuggers (caravanners) then so didn't pay much attention to it when my wife and i go back at Feb half term we will throughly investigate and report back with photos.
Val Disere - Possible though I was too busy tring to fiund a parking space for the car the day we went and can't remember much. Large carparks at the La Daille end of the resort with one M/H in but maybe as it was -20 Deg C the rest had moved on.
Be wary of where you park the police in Val Disere are very tight but nice, case in point Parking Ticket read "Thank you for your visit to our resort, you have parked in a restricted bay please move the vehicle". "If you need assistance on where to park please ask at the Police station". The car was left at 8.30am in a bay that seemed fine everyone else was there, the ticket was placed at 9.15am and we returned at 5.30pm didn't have to pay a thing. Can you imagine that inthe UK!!
All in all i think you need to contact the Tourist office in the area you are contemplating going and seek advice. One blessing is that you could access the highaltitude resorts of Les Arcs and Courchevel 1850 without paying a premium for accomm.
Costings.
Ferry? 120 - 250 depending on timing
Fuel How good is your MPG? We have driven there in winter for skiing and reckon on 950 Miles after off the ferry Calais and about £40 each way for tolls - Car pricing!!
Interesting post good luck see you on the piste!!
